NMSHEE Posted July 8, 2005 Report Share Posted July 8, 2005 I was wondering what fuel should i run in my banshee with 18cc domes,bored .040 over with some porting. At 5500 feet elevation? Thanks Quote Link to comment Share on other sites More sharing options...
namshee Posted July 8, 2005 Report Share Posted July 8, 2005 std with pipes the manufacturer indicates on the fuel tank "unleaded premium", but obviously the work done on your shee might require something else. Off hand would think the above would definitely be a safe bet...IMO Quote Link to comment Share on other sites More sharing options...
Rare Scottish Tree Badger Posted July 8, 2005 Report Share Posted July 8, 2005 What's your (cold) compression? Rare. Quote Link to comment Share on other sites More sharing options...

NMSHEE Posted July 8, 2005 Author Report Share Posted July 8, 2005 Im not sure what the cold compression is i will check it when i get it back together. Thanks Quote Link to comment Share on other sites More sharing options...
hittintrees srh Posted July 9, 2005 Report Share Posted July 9, 2005 I would run a 50/50 mix of premium and 110 or 112 race fuel. That will help prevent pinging and detonation. IMO Quote Link to comment Share on other sites More sharing options...
racer Posted July 11, 2005 Report Share Posted July 11, 2005 some octane boost. 390114[/snapback] Quote Link to comment Share on other sites More sharing options...
Banshee~ Posted July 11, 2005 Report Share Posted July 11, 2005 391055[/snapback] whats wrong with octane boost????? nothing. Its not as good as running a mix of race gas and pump, but its cheaper. Quote Link to comment Share on other sites More sharing options...
dlnoss Posted July 11, 2005 Report Share Posted July 11, 2005 You might be fine with 93 octane. I would check the compression to be sure. If it's over 160, mix some race gas or av-gas. At 20% to 50% race or av-gas isn't too expensive. Quote Link to comment Share on other sites More sharing options...
Dead Op Posted July 11, 2005 Report Share Posted July 11, 2005 You should be fine with 93 octane, look at his elevation. Quote Link to comment Share on other sites More sharing options...
racer Posted July 11, 2005 Report Share Posted July 11, 2005 octane boost is worthless, well not quite, but close. they are advertised to show large gains in the AKI rating. but in reality your MON only gows up about a tenth of what is advertised. ill see if i can find the thread where this was discussed in depth.

05bansh Posted July 13, 2005 Report Share Posted July 13, 2005 I say just spend the extra $$ and run straight race gas. I mean- its only your banshee were talking about...... Quote Link to comment Share on other sites More sharing options...
